  • Patent number: 12262421
    Abstract: A radio terminal (2) attempts to receive a second message of a 2-step random access procedure after transmitting a first message of the 2-step random access procedure. In response to successfully receiving the second message of the 2-step random access procedure and determining that the second message explicitly or implicitly indicates a fallback to a 4-step random access procedure, the radio terminal (2) further attempts to receive a control message that contains an uplink grant indicating uplink resources available for transmission of a third message of a 4-step random access procedure. This contributes to, for example, reducing the load on a radio terminal that supports a fallback from the 2-step random access procedure to the 4-step random access procedure.

  • Patent number: 12262269
    Abstract: A gateway is described which facilitates a change of communication cell for a mobile device in a communication system, which includes a core network. The gateway receives messages from a base station operating a cell and forwards the messages received from the base station to the core network. The gateway intercepts a message relating to a change of communication cell, from a source cell in which the mobile communication device is located to a target cell, to determine if the core network needs to be notified of the change of cell. When it is determined that the core network needs to be notified, the gateway generates a message for providing information relating to the change of cell to the core network and transmits the message to the core network.
